Update on Acetochlor Restrictions

Mark VanGessel, Extension Weed Specialist; mjv@udel.edu

Last week I wrote about the acetochlor restrictions. I was not aware that these restrictions had been modified and only pertain to applications within 50 feet of a well. The following restrictions do not apply for areas more than 50 feet from a well.

Within 50 feet of a well, do not apply acetochlor if the groundwater depth is within 30 feet of the surface and you have sands with less than 3% organic matter, loamy sands with less than 2% organic matter, or sandy loam with less than 1% organic matter.

Sorry about any confusion.
